I would venture to say 'no' to that, as "volcanic rock" is not a type of rock but a description of origin. Volcanic rock and sedimentary rock are not mutually exclusive; volcanic rock can and often leads to both metamorphic and sedimentary stratification. If indeed this rock is of volcanic origin (i.e. magma), then it would be more correct to say that the rock is not igneous instead of not sedimentary.
Anyhow, I have no guesses on this one.
Uhhh....what about all of the other states with volcanoes? Wyoming, Colorado, New Mexico, South Dakota, Idaho, Virginia, New Hampshire, Mississippi, Missouri, Nevada, and Texas all have at least one volcano.
I already had you guessed you as a geologist before this post.
I will be leaving New Hampshire out of the guessing though.
